Topic on Talk:Power Systems

There hasn't been a respond for around three years, so I am resolving it.

Can anyone help with adding example or help with the summary of the tropes?

X-Men has a certain gene that turns people into mutants. I think it's the "X-Gene" or something.

I am a bit iffy on that since the X-Gene is what makes them mutant. Mutations might what the trope describes but have people consider mutations are the term for a mutant's superpowers?
